NUT package (2.8.0 and below)

@kevindd992002 said in NUT package:

What I meant is when does the ups.delay.shutdown countdown start? When does the UPS start counting down before it cuts off power to its loads?

It starts when the UPS receives a shutdown command.

Do you have any ideas why is it that when I connect to my APU2C4 via a serial port, the NUT package cannot detect my USB UPS?

As soon as I remove the serial cable connection and restart NUT, it works just fine.

Serial or USB ?

? Without the cable, NUT works ?

APC UPS is connected via USB and I'm trying to keep a serial connection alive but when I do that it kills the APC USB connection. It only happens for the APC USB connection, not with other USB devices.

Yes, it works without the serial connection.

@kevindd992002 This is a basic NUT issue rather than a package issue. You'll need to diagnose this at the NUT level, and probably follow up with the NUT forum. I'd suggest you start by examining the log entries for NUT...

So I am able to monitor and query the values of the two ups that power my firewall, by adding a second one at Advance Settings under ups.conf

Any tips on what files, and their location the status widget uses to be able to modify and display data for each of the ups. (Hopefully something as simple as adding a loop or hardcoding a link for the second entry).

dennypage · Aug 2, 2021, 9:45 PM

@josepr The pfSense NUT package is designed to supervise/monitor a single UPS only.

I'm curious as to why you have two UPSs on your firewall... does you firewall hardware have dual power supplies connected to separate UPSs?

josepr · Aug 2, 2021, 10:03 PM

@dennypage
Two ups each ones feeds a pdu which feeds a dual power supply host and other dual power equipment on a small 12U rack.
I am comfortable with programming and some html so wanted to see if could modify my copy of the package locally on my machine and make it work.

josepr · Aug 3, 2021, 1:27 AM

@josepr
So was able to find the widget php and for now hardcode the second ups, havent had the chance to play with php before but will try to make it so that it can read all ups from the ups.conf and do something like the traffic or gateway widget were i can select which to display, get a chance to learn php.

I see. Old school cool. Given the lower cost of hardware these days, I don't see that much anymore. These days I usually see dual systems, each with their own UPS, set up as a fault tolerant or load balanced pair. But you probably have that as well.

Unfortunately, while NUT itself has support for multiple power sources, the pfSense NUT package does not support that configuration. The pfSense NUT package is single UPS only. It would take quite a bit of work to make it support multiples in the various (extensive) configurations, and there really hasn't been any interest. You are actually the first to ask about it.

Probably your best bet is to use one of your other systems to run NUT on, and have that system initiate a remote shutdown of pfSense when the time comes. Sorry.

@josepr
Well I have it working for at least a nice widget displaying all the info for the attached ups, which was my main goal so i can get an idea of their status in one page, dont really have it shutting down anything at the moment maybe will get to that later.

For anyone that is interested all I did was:

Modified '/usr/local/pkg/nut/nut.inc'
Added two functions:

function nut_conf() {
	global $config;
	$conf = &$config['installedpackages']['nut']['config'][0];
	return $conf;
}

function list_ups() {
	$upss = array();
	$config = nut_conf();
	if (isset($config['name'])) {
		$upss[] = $config['name'];
	}
	if (isset($config['ups_conf'])) {
		$conf =  parse_ini_string(base64_decode($config['ups_conf']), true);
		foreach ($conf as $name => $_conf) {
			$upss[] = $name;
		}
	}
	return $upss;
}

and modified the start of the nut_ups_status function

function nut_ups_status($name = null)
{
	global $config;
	$status = array();

	$nut_config = &$config['installedpackages']['nut']['config'][0];
	if (isset($nut_config['type'])) {
		$type = $nut_config['type'];
	} else {
		$type = 'disabled';
	}

	if ($type == 'disabled') {
		$status['_summary'] = "Monitoring is not enabled";
		return $status;
	}

	$ups = $name ?: $nut_config['name'];

Then i modified /usr/local/www/widgets/widgets/nut_status.widget.php

<?php
require_once("/usr/local/www/widgets/include/nut_status.inc");
require_once("/usr/local/pkg/nut/nut.inc");


if ($_REQUEST && $_REQUEST['ajax']) {
	print_all_table(); #Get multiple tables instead of just one.
	exit;
}


function print_row($desc, $value) {
	#didnt touch
}

function print_row_pct($desc, $value) {
	#didnt touch
}

function print_table($name) {
	$status = nut_ups_status($name);
        ##Only added the $name parameter, the rest stayed the same
}
#New Function to print a table per UPS
function print_all_table() {
	print '<table class="table table-bordered table-dark"> <tbody>';
	foreach (list_ups() as $name) {
		print '<tr class="panel-title"><td><b>' . $name . '</b></td></tr>';
		print '<tr><td><div">';
			print '<table class="table table-striped table-hover table-condensed">';
			print '<tbody>' . print_table($name) . '</tbody>';
			print '</table>';
		print '</div></td></tr>';
	}
	print '</tbody></table>';
}
?>
<div class="table-responsive" id = "nuttable">
	<?php print_all_table() ?>
</div>

<script type="text/javascript">
#Didnt touch
</script>

And then add my second ups under the ups.conf advanced settings.

@josepr It might be a good idea to focus on correct NUT configuration before worrying about the monitoring widget. It appears that you've set up a situation in which the pfSense box will shutdown if either UPS fails, which I'm pretty sure is not what you want. For the work that you're doing, it would be simpler to abandon the pfSense NUT package and just configure NUT directly. Of course, you'll loose the pretty widget, but it would be a lot safer.

The APC UPSs are SNMP based, and also have their own web interface. Is there a reason you are focused on having status displayed in pfSense widgets? Instead of using their built-in web monitoring? Or an SNMP web based monitor such as Librenms or the like?

@dennypage
Actions are not taken for the device configured at ups.conf, this is only for the upsd service which setups communications with devices and can also provide access to this devices to other remote services such as a remote upsmon instance in another server.
upsmon is the service that actually enforces action and it has its own configuration which the package only generates an entry for the UPS configured the normal way, I did add a two liner to the Advance part so that it acts when both UPS are down.

Auto generated by the package for UPSMON

MONITOR ups-2 1 local-monitor **** master
SHUTDOWNCMD "/sbin/shutdown -p +0"
POWERDOWNFLAG /etc/killpower

With addition to the upsmon.conf at advance in gui

MONITOR ups-2 1 local-monitor **** master
SHUTDOWNCMD "/sbin/shutdown -p +0"
POWERDOWNFLAG /etc/killpower

###ADDED LINES upsmon.conf####
MONITOR ups-1 1 local-monitor2 **** master
MINSUPPLIES 1

Did also have to add an extra user in upsd.users as the package generates a random password everytime it saves for local-monitor

[local-monitor2]
password=****
upsmon master

This tells upsmon that it should monitor the 2 ups, that both UPS provide power for one PSU in the server and that it needs a minimum of one power supply to operate, so it is now fault tolerant (Will only conduct a shutdown if both UPS are down/critical power).

The reason i add them to PFSENSE is that it depends on both UPS so I wanted a way to make sure it reflected this and didnt try anything drastic when one UPS is offline.
It is my always on device and the last device to be shutdown and can it act as a ups provider to any other nut clients in other devices.

MINSUPPLIES was not shown in the configuration you posted previously.

@dennypage
Yes, but i also hadnt added
MONITOR ups-1 1 local-monitor2 **** master
to upsmon so it was not watching/monitoring the second ups.

@gooberpatrol66 You haven't included the pertinent portions of your config, but best guess based on the log is that you are simply not able to connect to the UPS.

Be sure that you are referring to the UPS by address. Don't depend upon host name resolution for a UPS.
Confirm that you can actually access the UPS with the SNMP credentials specified.

Unrelated, but a poll frequency of 1 is really overkill. The default of 5 works just fine. The lowest poll frequency recommended by NUT is 2.

There was a blackout in my house a few days ago. I've noticed a very weird behavior with my Eaton UPS while I was actually monitoring the shutdown process. Here are the logs:

Oct 11 09:47:04 	upsmon 	18273 	UPS ups battery is low

The weird behavior was that after the UPS gets a shutdown command from pfsense NUT, it shuts itself down, cuts power off from the load and then turns back on right away even though there is no power from the mains yet. And then it shuts itself down again and continues this cycle until the battery gets depleted. Any ideas what's causing this?

Also, at 9:48:21 I see a logout from one of the remote monitors, but why is there another login event at 9:48:25 right before the shutdown event by root at 09:48:27?

Gertjan · Oct 12, 2021, 2:26 PM

@kevindd992002 said in NUT package:

Any ideas what's causing this?

The BIOS of your pfSense uses the setting "Auto power on when power comes back".
So, when the power comes back, it will boot again.
This will loop until a) the power comes back and b) the battery is charged enough so NUT decides to stay 'on'.

Easiest solution : don't auto boot when the power comes back. This means that the shut down is controlled, but human presence is needed to switch it on again.
Best solution : Have a talk with your USP. Ask it to power the oullets when a and b or ok.
This best solution is often not possible with a typical SoHO UPS.
